John Schwandt directs the American Organ Institute, the only school in the world that trains pipe organ builders. But Schwandt is equally a world-class performer and improvisator, as this new holiday release illustrates. Using surprisingāand often comicātune pairings such as āDeck the Halls with Frankincense and Myrrh on a Clear Midnight,ā Schwandt plays up a storm. The improvisations are as thrilling as they are ingenious. The disk ends with the University of Oklahoma choirs joining Schwandt for Silent Night. (Order by emailing aoi@ou.edu.)
